IV_INO_LBLK_32 policies introduced the possibility that logically contiguous data blocks might not have contiguous DUNs (because of potential DUN wraparound). As such, whenever a page is merged into a bio, fscrypt_mergeable_bio() must be called to check DUN contiguity. Further, fscrypt inline encryption does not handle the case when the DUN wraps around within a page (which can happen when the data unit size != PAGE_SIZE). For now, we handle that by disallowing inline encryption with IV_INO_LBLK_32 policies when the data unit size != PAGE_SIZE (and dropping the now redundant check for this in fscrypt_dio_supported()).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
